WELL-TILING COUPLER.

SPECIFICATION forming part of Letters Patent No. 491,956, dated February14, 1893. Application filed February4, 1891. Renewed August 13, 1892.Serial No. 442,970. (No model.)

To al whom it may concern:

Be it known thatl, WILLIAM A. SUMNER, a citizen of the United States,residing at Clay Center, in the county of Clay and State of Nebraska,have invented certain new and useful Improvements in Well-TilingCouplers; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters of referencemarked thereon, which form a part of this specification.

The object of this invention is to provide an improved tool for loweringlining tiles or tubes into Artesian Wells, so that the work can beexpeditiously performed, and the successive tile sections squarelyseated on those beneath, and to this end the invention consists of thewell tiling coupler or tool hereinafter described and claimed.

Figure 1 is a perspective view of the coupler, and Fig. 2 is a sectionalview of a well, showing the operation of the tool.

A is the head, provided with a ring a, to which the suspension rope A isattached.

B B are two arms of spring metal, attached on opposite sides of the headA. These arms extend downward and outward, and at their lower ends, B,curve inward and form the tripping device by which the tool is releasedfrom the lining tile when lowered into place, as hereinafter described.The arms B are attached to the head A by means of a single bolt passingthrough the arms and the base of the head, and each arm is provided witha thumbscrew C, by means of which a greater or less spread can be givento the arms to fit the tool to pipe of different sizes.

D D are flat bars pivoted or coupled together at their lower ends, andrespectlvely pivoted or hinged to the arms B B at their upper ends.These bars form a V, and the upper end of each has a shoulder orprojection D, which projects out beyond the arms B, and on whichshoulders the tiles rest while they are being lowered into place.

The head A has attached thereto a bent U shaped rod E, placed in a planotransverse to that of the arms B, which bent rod steadies the tiles'andholds them in a vertical position while they are being lowered.

The operation of the coupler is as follows:

A tile F is placed thereon, as illustrated by 5 5 Fig. 2, so that thebottom edge of the tile rests on the projections D, and as many othertiles on top of the same as may be desired. A dozen tiles can thus belowered at once.

They are then lowered down the well, and as 6o the bottoms of theinwardly curved ends B of the arms B enter the top of the section oftiling F, already set, the tool automatically aligns itself, and if itshould not strike the tile F true and square it swings into correctalignment.

It should be observed that the Outside span of the arms B at theirwidest point is the same as the distance across between,the extremitiesof the projections D, which distance is of course greater than that ofthe inner diameter of the tile, and hence, as the coupler is lowered,after the ends B of the arms enter the said tile F, the spring arms aregreatly compressed, and when the arms B are entirely within the tile Fthe shoulders D are drawn in sufficiently to permit the tile F to dropinto place true and'square on top of the tiles already seated.

Having thus described my invention, what 8o I claim as new, and desireto secure by Letters Patent, is

1. A well tiling coupler, having movable lateral projections to supportthe tile, and spring arms attached to said projections and having lowercurved portions extending down below and laterally beyond the same, forthepurpose of detaching the coupler, substantially as and for thepurpose set forth.

2. The combination, in a well tiling coup- 0 1er, of a pair ofdownwardly extending spring arms, curvinginward at theirlower ends, withtheV-shaped hinged bars coupled to the spring arms respectively, andhaving shoulders extending out beyond the spring arms, substan- 5 tiallyas and for the purpose set forth.

3. The combination, in a well tiling coupler, of a head having a pair ofadjustable spring arms extenc1ing downward, with in- In testimonywhereof I {LffiX mysgnaturein ward1y curved ends, with theV-shapedhinged presence of two wtnesses. bars coup1ed to the springbars, and having shou1ders extending out beyond the spring VILLIAMSUMNER' bars, substantially as described, together with Vitnesses:

the transverse guide-rod for steadying the IIATTIE MOULTON,

tile, as and for the purpose set forth. A. C. EPPERSON.
